If your 2015 Suburban 1500 is acting possessed—with flickering lights, malfunctioning power windows, a dead radio, or random warning messages—you’re not alone. As a technician with over two decades of experience, I’ve seen these exact electrical gremlins countless times. The culprit is almost always a failing Body Control Module (BCM), the central nervous system for your vehicle’s comfort and convenience features.
A failing BCM can turn your reliable SUV into a source of daily frustration. Dealerships will often quote you a staggering price for a new module, followed by additional charges and delays for programming. Our service is designed to be the simple, cost-effective, and reliable alternative. We provide a fully programmed BCM, ready for installation, by cloning the essential data from your original unit.
The Smarter Solution: Plug-and-Play BCM Cloning
Forget about towing your vehicle to a dealer or struggling with complex programming tools. Our process is straightforward: you purchase this service, we provide instructions for you to ship your original BCM to our facility, and our expert technicians handle the rest. We extract the unique vehicle-specific data from your faulty module and transfer it directly onto a replacement unit. This ensures that the new BCM is a perfect digital match for your Suburban, retaining all its original settings and security information. We then ship the ready-to-install module back to you, typically within a few business days. It’s a true plug-and-play solution that gets you back on the road without the dealership headache.
Case Study: A Tricky Diagnosis
I remember a 2015 Tahoe (which shares this exact BCM with the Suburban) that came into my shop with a bizarre list of complaints. The power locks worked intermittently, the dome light would stay on, and the driver’s side window wouldn’t go down. The owner had already replaced the battery and checked all the fuses. A basic scan tool showed no communication with several modules. After tracing the CAN bus network, we isolated the fault to the BCM. A failing internal processor was corrupting data packets, causing chaos across the vehicle’s network. By cloning his original BCM, we preserved the vehicle’s key data and had all systems restored in under an hour of shop time post-install. This is a classic BCM failure scenario.
Is Your Suburban Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system acting up or preventing the engine from starting.
- ✔ Horn, windshield wipers, or radio not functioning correctly.
- ✔ False warning messages on the dash, such as ‘Service StabiliTrak’ or ‘Service Airbag’.
- ✔ Communication loss diagnostic trouble codes (DTCs), like U0140, U0155, or U0100.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2015 Suburban 1500, the BCM is typically located under the steering column, behind the lower dash panel. You may need to remove a few plastic trim pieces for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your pre-programmed BCM in the same location and securely reconnect all the electrical harnesses. Ensure they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions—lights, locks, windows, radio, etc.—to confirm proper operation.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some GM vehicles may require a simple relearn procedure for specific systems. This is normal. You may need a professional scan tool for the following:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal sensor recalibration may be required to ensure brake lights and traction control function correctly.
And the best part? There is no core charge. You can keep your original module. This service is for a replacement BCM that fits part numbers 13594692, 13594768, 13593214, 13580690, 13591519, and 13594769.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will contact you with simple instructions to ship your original BCM to us. Our technicians will then transfer all the critical data to a replacement module and ship it back to you, ready to install.
Is this a plug-and-play solution?
Yes, because we clone your original data, this BCM will be plug-and-play. It eliminates the need for expensive dealership programming. In some rare cases, a minor relearn procedure like for the brake pedal sensor might be needed.
Will this fix my specific electrical problems?
This module corrects issues directly controlled by the BCM, such as power locks, windows, lighting, security, and wipers. If you’re experiencing multiple, seemingly unrelated electrical failures, a faulty BCM is the most likely cause.
What part numbers does this replace?
This service and replacement module are compatible with part numbers 13594692, 13594768, 13593214, 13580690, 13591519, and 13594769.
Do I need to send my keys?
No, you do not need to send your keys. The necessary security information is stored within the BCM itself, which we transfer during the cloning process.
How long does the process take?
We typically program and ship the replacement module the same or next business day after we receive your original unit. We will send you tracking information as soon as it ships.
